Action specification:

Fig. 9 is the power that path CD d resists second extension spring 29, inserts mouthfuls 5 CD conductor 7 and transports state when inserting between the roller 27 from CD.At this moment, the periphery of path CD d promotes test section 10a, the 11a of two test rods 10,11, makes two test rods turn to the position shown in the solid line from the position shown in the imaginary line (dotted line).The rotation of two test rods 10,11 makes interlock plate 13 be moved upward from the position of imaginary line (dotted line).Moving of this interlock plate 13 makes first switch, 16 closures, and motor 30 is started.Motor 30 drives by reducing gear and transports roller 27 rotations, and path CD d is moved in the CD motion path 4 by transporting the rotation of roller 27.At this moment, the breach 40b and the worm gear 36 of cam gear are in corresponding position, so the rotation of worm gear 36 can not make cam gear 40 rotate.Then, rotate, transport in the path Yi Bian be introduced in CD on one side path CD d promotes two test rods 10,11.

If the path CD is not aimed at the center that CD inserts mouth 5 when inserting, one of them little by little rotating only can appear in two test rods 10,11, first switch, 16 closures, path CD d is transported to CD by the rotation of transporting roller 27 and transports within the path 4.Thereafter, owing to contacting of stage portion 2c and fitting portion 13b, left and right sides test rod 10, the 11 wherein rotation of a side is limited.Like this, path CD d will by transporting the rotation of roller 27, be transported to CD and transport in the path 4 near center line 1a under the guiding of the test section that is limited to rotate a side.

Under the rotation of left test rod 11, the second slotted hole 11e makes control lever 20 rotate according to the clockwise direction among the figure by salient point 20b.Because this control lever 20 is installed according to line and the center line 1a direction arranged side by side of the first minor axis 20a, the second minor axis 20c, therefore, the frizzen 21 that the rotation front end of Be Controlled bar 20 supports will move along the direction that faces center line 1a.Like this, by the mode that frizzen 21 is moved towards the direction that faces center line 1a, can effectively control the size of main frame on the CD carriage direction of the disk player in the utility model.

The center of the center that Figure 10 has shown path CD d by plummer 12 little by little, the state that the periphery of path CD d and baffle portion 15a touch.At this moment, the contact site 21a of frizzen 21 withstands on the periphery of path CD d, and the contact plug 21b of frizzen 21 moves to the represented position of solid line near the center from the position of imaginary line.By the rotation of this frizzen 21, the arc groove 40f of the contact plug 21b of frizzen pushing cam gear 40 makes cam gear 40 to counterclockwise rotating.By the rotation of this cam gear 40, the gear ring 40a of cam gear 40 and worm gear 36 engagements.Motor 30 makes cam gear 40 to counterclockwise rotating by worm gear 36.By the rotation of this cam gear 40, the first flange 40c will make chuck 22 near plummer 12 by grip block 23.Then, the clamping plate shell fragment 24 that is installed on the grip block 23 is pushed path CD d to plummer 12 by chuck 22.

On the other hand, the second flange 40d of cam gear 40 is by the second slide connecting part 26b of PU substrate 26, and making PU substrate 26 is that rotate at the center with rotating shaft 26a.Be accompanied by this rotation, PU substrate 26 promotes rotating mechanism 25, makes plummer 12 near path CD d.Plummer 12 and chuck 22 make the broadcast of CD become possibility together with the clamping of path CD.On the relative face of plummer 12 and chuck 22, be provided with the pyramidal projections 12a that the center pit with path CD d cooperates, after the center pit of path CD d and this projection 12a were chimeric, the periphery of path CD was disengaged with contacting of baffle portion 15a.

And with reference to Fig. 7, the 3rd flange 40e of cam gear 40 is by the rotation of cam gear, and under the state of opposing second extension spring 29, making roller support plate 28 is that rotate in the counterclockwise direction at the center with rotating shaft 28b.Counter clockwise direction by this roller support plate 28 is rotated, path CD d and transport roller 27 and move to the direction of infrabasal plate 3 together, and path CD d is dropped on the plummer 12.Then, rotate by the counter clockwise direction of roller support plate 28, taper is transported roller 27 and is left path CD d, moves to the position that can not hinder CD to rotate.On the other hand, the path CD drops on the plummer 12, has also just left CD conductor 7.

And, cam gear 40 rotation terminal in the counterclockwise direction, the second projection 40h of cam gear 40 and the 11d of foot of left test rod 11 contact, and left test rod 11 is rotated to counter clockwise direction in Figure 10.Left side test rod 11 makes test section 11a leave the periphery of path CD by this rotation.In addition, the right test rod 10 by interlock plate 13 and 11 interlocks of left test rod in Figure 10, moves in the direction of the clock, and makes test section 10a leave the periphery of path CD.That is to say, path CD d from CD insert mouthfuls 5 insert after, be transported on the plummer 12, then by chuck 22 clampings, test section 10a, 11a are always to the periphery channeling conduct of CD during this.By this guiding, what kind of posture no matter the disk player in the utility model be in, all can being transported on the plummer 12 path CD d safety.In addition, in the taking-up operation of CD, above-mentioned action is then carried out conversely.Like this, path CD d is by after two test section 10a, the 11a clamping, and the clamping of chuck 22 and 12 pairs of CDs of plummer just is disengaged, even the direction of CD insertion mouth 5 down, can prevent that also the path CD from dropping out from CD insertion mouth 5.

Figure 11 has shown that path CD d is maintained at and has been in the state that can play on the plummer 12.At this moment, cam gear 40 is positioned at the terminal location of rotation, and the periphery of test section 10a, 11a and baffle portion 15a and path CD d is in contactless state, CD conductor 7, transports roller 27 and also is in contactless state with cd side.Under the effect of the second projection 40h of cam gear 40, left test rod 11 is subjected to anticlockwise rotating force, and interlock plate 13 only has minute movement.Because the minute movement of this interlock plate 13, fitting portion 13b moves in the first bullport 2a by stage portion 2c.Therefore, when CD was taken out, path CD d was transported out under 7 the clamping of transporting roller 27 and CD conductor, because fitting portion 13b discord stage portion 2c contact, so it is very smooth and easy to take out action.

Figure 12 has shown that big footpath CD D is from inserting a mouthful insertion, the state the when amount of spin of two test rods 10,11 reaches maximum.Left side test rod 11 is under it rotates, and the second slotted hole 11e makes control lever 20 rotate to greatest extent according to the clockwise direction among the figure by salient point 20b.Be installed on the frizzen 21 of the rotation front end of this control lever 20, move towards doing maximum magnitude over against the direction of center line 1a.Like this, because frizzen 21 moves towards the direction over against center line 1a,, still can suppress the increase of main frame 1 size on the CD carriage direction even the rotation of left test rod 11 reaches to greatest extent.Rotation at two test rods 10,11 reaches in the process of maximum magnitude, and first 13c of pushing portion of interlock plate 13 pushes the compression zone 15b of CD baffle plate 15 to, as shown in figure 15, the baffle portion 15a of CD baffle plate 15 is withdrawed from from transporting the path 4 of CD.Therefore, transport big footpath CD under the situation that can contact at the baffle portion 15a of discord CD baffle plate 15.

Figure 13 has shown that big footpath CD D contacts with baffle plate 6, the feasible state that moves when stopping that transporting, being centered close to of big footpath CD just surpasses a little position, plummer center, at this moment, the contact site 21a of frizzen 21 is pushed to the periphery of big footpath CD D, frizzen 21 is the center with the second minor axis 20c, turns to the position of solid line from the position of imaginary line (dotted line).By the rotation of this frizzen 21, the end face of the arc groove 40f of the contact plug 21b actuating cam device 40 of frizzen 21 makes cam gear 40 to counterclockwise rotating.By the rotation of this cam gear 40, the gear ring 40a of cam gear 40 and worm gear 36 engagements make the rotation of motor 30 can be delivered to cam gear 40.

Cam gear 40 is turning to end to counter clockwise direction, and the 11d of foot of the 3rd projection 40g and left test rod 11 contacts, and as shown in figure 13, makes left test rod 11 to counterclockwise rotating.Rotate by this, the test section 11a of left test rod 11 leaves from the periphery of big footpath CD D.Then, by chuck 22 CD D is remained on the plummer 12.Because big footpath CD D rotates two test rods 10,11 significantly, the amount of movement of interlock plate 13 also becomes greatly, and consequently the 3rd 13e of pushing portion makes second switch 17 actions, is in the state of connection.Second switch 17 is in after the on-state, will send signal, shows that the CD that is inserted is big footpath CD.

Figure 14 has shown that big footpath CD D is positioned on the plummer 12, is in the state that can play.At this moment, cam gear 40 is positioned at the terminal location of rotation, and the periphery of two test rods 10,11 and baffle plate 6 and big footpath CD D is in contactless state, in addition, CD conductor 7, transport roller 27 and also be in contactless state with cd side, the broadcast of CD becomes possibility.

In the above-described embodiments, be maintained on the plummer 12 until the path CD, test section 10a, 11a are contacted with the periphery of path CD d, but, as long as be positioned within the scope that can be maintained on the plummer 12, can allow test section 10a, 11a leave from the periphery of path CD at path CD d.At this moment, described releasing parts 40 will not need.In addition, be provided with stage portion 2c on upper substrate 2, limit it and move when interlock plate 13 rotates, this function also is unnecessary.That is to say, for the path CD d that is transported on the plummer 12, under the elastic force effect of first extension spring 14, can be to (the path CD is when transporting because of the deadweight of path CD d and because of transporting one-sided the transporting that roller causes, can be partial to the big side in tapered roller footpath, cause departing from the center of transporting the path.) correct, make it near center line 1a direction.

The utility model can be used for disk players such as CD, DVD.
